MACHINE FOR LOCATING AND STAMPING MATRIX-BARS.

SPECIFICATION forming part of Letters Patent N 0. 627,160, dated June 20, 1899.

' Application filed September 15, 1898. Serial No. 691,050. (No model.)

To all whom it may concern.-

Be it known that I, EVERARD VAN DER WEE, mechanic, of the city of Rochester, in the State of New York, have invented certain new and useful Improvements in Machines for Locating and Stamping Matrix-Bars, of which the following is a specification.

My invention relates to, improvements in letter locating and stamping machines for matrix-bars; and the object of the invention is to produce the type-letters of matrices for line-casting machines in a simple, cheap, and

positive manner and by which a perfect alinement of the type in a line of type whencast is insured; and it consists, essentially, of a suitable bed-plate having a suitable gagingrib, which, corresponding with notches of the matrices to the letters required in the alinement, are designed to be placed to hold such matrix from longitudinal displacement, end blocks being also provided to provide for the different thicknesses of the matrix-bars, such rib and blocks being supported upon a suitable longitudinally-adj ustable block operated through a suitable plunger and inclined recess in the rear portion of the block and a pressure-spring, an upper guiding-block being provided for the plunger into an aperture, in the front of which is placed each punch, which when the matrix-bar is in position is located directly over the notch designed to receive the impression, the parts being constructed and arranged in detail, as hereinafter more particularly explained.

Figure 1 is a sectional perspective view of my locating and stamping tool. Fig. 2 is a cross-section on a line with the center of the punch. Fig. 3 is a plan View showing the front portion of the guiding-block partially broken away to exhibit the position of the matrix-bar.

In the drawings like letters and numerals of reference indicate corresponding parts in each figure.

A is the bed-plate of my locating and stamping tool, which is suitably and securely held on a bed-plate of any form of press, and a is an aperture, preferably rectangular, extending through the rear end of the bed-plate A.

B is a three-sided frame, which is suitably secured to the bed-plate A and is provided with a central front aperture b. O is a rectangular block having a central rectangular opening 0 with an inclined rear side. The front of the block 0 is provided with a raised overhanging portion 0 The block 0 fits within the aperture 1), the rear end of the block 0 being provided with the cross-recess 0 directly opposite a crossrecess 1) in the back portion of the frame B. Fitting within the recesses c and b I provide a flatcurved spring D, the normal tendency of which is to force the block 0 forwardly.

E is a block fitting within the opening 0, near the front end thereof.

G G are the two portions of the upper guiding-block. The two portions G and G are secured together by suitable bolts g, extending through them from side to side and to the sides and ends of the frame B by the caps'crews 2.

It may be stated that the section shown in Fig. l is not through the center ofthe machine, but to one side thereof, and that the inner side is shown in thisfigure. The longitudinal center section of the machine would be, however, the center of the rectangular punch H, which is shown in full in. this figure fitting within a corresponding aperture G at the front of the guiding-blocks G G. The bottom of the punch H is tapered, as shown, and is provided with the usual type,embossed or otherwise formed on the lower end thereof.

I is a plate which is secured to the front of the upper guiding-blocks G G by suitable screws 1). The plate retains the punch H in position at the front. It will be noticed that the punch H extends normally slightly above the level of the guiding-blocks G G and is held in such position by the spring-rod 7t, which extends through it and through the hole H, extending from side to side of the guiding-blocks G G at the front. i The ends of the rod h are supported byscrew-nuts 1-1 through which they freely extend.

To place another punch in position, it is simply necessary to unscrew one of the nuts H and remove the rod, when another punch may be placed in position and the. rod inserted through it and held in position, as before. When in position, it will of course be understood that such rod acts as a support for the punch, restoring it to its normal position after it has been struck to stamp a letter or character upon the matrix.

E is a cross-bar, of hardened steel, dovetailed in cross-section and fitting in a correi machines will be understood by those skilled in the art, so it will be unnecessary here to describeit further, except to show the use to Which the notchesj may be adapted in sta1nping the different letters and characters.

6 is my gage-bar, which is fitted in a groove 6 extending from the front to near the rear of the block E, at the top thereof.

cross-recess g the bottom of the guiding-blocks G G.

K is'the block situated in front of the stophlockG and provided with the cross-groove Fitting Within the opposing grooves g and I provide a flat curved spring 70 (shown in 1 full lines in Fig. 1 and dotted lines in Fig. 3) and designed to normally press the block K forwardly.

It will be noticed that the matrix-bar J fits directly in front of the block K and is held in position between the block K and the front block L, which is L-shaped in cross-section and isadjusted up to this position against the matrix-bar J by the set-screws M, extending" through the portion 0 of the block 0. block L is of course held down in position by meansof the forward lower extension I.

fr'ear inner side of the block 0. The plunger; N extends through an aperture 3 in the up-. per guidingblocks G G.

Heretofore it has been common in stamp-E ing the letters and other characters on Ina-- tion, and thus'produce a line of type when "cast with perfect alinement.

Another defect arose 1n elnploylng a gang of punches simul- The taneously to stamp each matrix-bar from the fact that it was difficult to get the bottom of the punches even. In fact it was almost impossible to do so. It must be remembered that an infinitesimal difference would produce great defects in printing, and this has been found actually to be the case that some letters would print dark and others light, and thus produce very poor printing. To overcome these defects my invention was designed, in which it will be noticed that as the top of the punch projects above the top of the guiding-block but a small distance such punch necessarily can only be depressed such a distance. Consequently every matrix-bar must have the type stamped so that the'sunken portion is exactly on a level.

The operation of my invention is as follows: In the position shown in the drawings in Figs. 1 and 2 the matrix-bar is shown with one of the notches j straddling the guidingrib e The plunger J is also shown in Fig. 1 down, so as to hold the matrix-bar in position directly underneath the punch H. 133* striking the punch H the desired stamp of letter is imparted to the bottom of the notch j By raising the plunger N until the beveled end comes opposite the inclined side at "G is a stop-block provided with a front. The block G is secured to the rear of the block 0 it will be seen that such block will be forced forward by the movement of the spring, so as 'to throw the matrixbar to the front of the plate I, when it can be readily removed and another matrix-bar placed in position. By lowering the plunger N the newly-placed matrix-bar will be placed in position directly underneath the punch to receive the impression when the punch is struck, and so on.

ing machines there are usually eight matrixbars containing twelve notches and blanks ji in each, making really ninety-three letters N is a plunger having a beveledbottom end n, which is designed to coact with the inclined and characters and three blanks. In changing my matrix-bars instead of changing the whole bar by a gang-punch, as hereinbefore described, I'would use the same punch for each letter of the corresponding notch whether fifty or any number of matrix-bars, depending on the number of sets required to be used in the machine. After the required number have been stamped with one letter I remove the punch H and place acorrespondin g punch containing the next letter desired to be stamped on the matrix-bar, and so on, thereby insuring in each matrix-bar and in'each'c'orresponding notch thereof an identical position for the letter of such notch. It will there fore be understood that by stamping't'he letters in each recess or notch separately the position of each individual letter is accurately located, so that every line of type will be in perfect alinement, and the printing from such line of type necessarily so.
